Investigators raided the offices of eTurboTouch on Tuesday last week after receiving a tip-off from TPK that former employees allegedly stole company trade secrets before moving to eTurboTouch, TPK said in a statement.

TPK said it suspects that employees at its subsidiary MasTouch Optoelectronics Technologies Co Ltd (展觸光電) were involved.

MasTouch makes touch panels used in notebook computers.

Prosecutors from the Taoyuan District Court are investigating the allegations, the company said.

ETurboTouch, which makes touch panels for laptops, yesterday sued TPK chairman Michael Chiang (江朝瑞) and other company officials for libel.

ETurboTouch has also reportedly filed petitions to various government agencies demanding the authorities examine if TPK is damaging market competition, according to Chinese-language Web site MoneyDJ.com.

In response, TPK said it only seeks to protect its intellectual property (IP) rights and does not engage in anti-competitive practices.
